We are proud to offer KSS's unique advantages to our clients. Those clients range from the most
experienced professionals to the novice building their first boat. KSS is the method of custom
boat building which is applied to all Kelsall and non-Kelsall designs.

Having pioneered the use of foam/fiberglass sandwich construction, Kelsall Catamarans has c
ontinued to develop and refine the use of these materials. KSS is the only build method to
have ever been subject to regular development and is more efficient than any alternative.

Resin infusion became standard for Kelsall Catamarans five years ago, as the perfect partner
to the mould table. Applying resin by hand is never a pleasant occupation, especially into
difficult to reach areas. Kelsall clients tell us how satisfying they find resin infusion.
Particularly those who have done it the hard way before. One project in China saw the women
excelling at setting out and applying resin infusion techniques.
The standard materials and equipment applies to the typical one-off project. Large or
commercial projects for longer term will depend on size and other circumstances. Resin
infusion is a simple process - air is sucked from the bag creating voids around the glass
fibers and in the resin flow media. Resin is then allowed to flow into the spaces between
fibers etc, replacing the vacuum. A high vacuum is applied to the bag before the taps are
opened to allow the resin to flow. 2-3 hours are enough for the larger panels.
The set up needed on the table is also simple. However, there are many different ways of
achieving good results. We pass on our knowledge gained over many projects to builders with
RI Guidelines with designs. There are also many others using RI and many suppliers. Usually
we find that no two RI shops are run the same way. Hence, not all shops will have the same
equipment or materials. We recommend that you start with a test panel before starting main
laminating, and to recognise a quality laminate.
